Closed Head Injury Subdural Hematoma
Closed Head Injury Subdural Hematoma A closed head injury subdural hematoma is a serious brain injury. It happens when blood gathers between the brain and its outer covering without breaking the skull. This injury is often caused by head trauma and needs quick medical help.
It’s important to know how this injury works, spot the signs, and find ways to treat it. This guide is for anyone in the U.S. who cares about someone with this condition. It will make things clearer about subdural hematomas, their causes, and how to get better.
We will look closely at head injuries and brain bleeding in this article. We’ll share important facts from neurology to help you understand and deal with this serious health issue.
What is a Closed Head Injury?
A closed head injury happens when the head hits something but doesn’t break the skull. Yet, it can still hurt the brain a lot inside. Knowing about the types, causes, and signs is key to handling these injuries well.
Definition and Types
There are two main kinds of closed head injuries: concussions and brain contusions. A concussion is when the brain gets jumbled but usually gets better. A brain contusion is when brain tissue gets badly bruised and can cause serious problems. Both are types of head injuries that don’t go through the skull.
Common Causes
Closed head injuries often come from different events, such as:
- Falls: Taking a tumble can cause a big hit to the head.
- Vehicle Accidents: Crashes can lead to strong hits on the head.
- Sports Injuries: Sports like football and soccer increase the risk of head injuries.
- Physical Assaults: Being hit hard in fights can cause serious brain injuries.
Symptoms to Look for
It’s important to know the signs of a closed head injury. Look out for:
- Confusion and disorientation
- Nausea and vomiting
- Dizziness and balance issues
- Blurred or altered vision
- Loss of consciousness
If you see any of these signs, get medical help right away. It’s crucial to know the signs of a concussion or brain contusion to help the injured person.
Understanding Subdural Hematoma
A subdural hematoma is when blood gathers under the brain’s outer layer. It’s important to know about it for quick and right treatment.
What is a Subdural Hematoma?
It happens when blood collects on the brain’s surface. This can be from a head injury. It puts pressure on the brain and can cause damage.
Knowing the signs like headaches, confusion, and trouble moving is key.
Types of Subdural Hematomas
There are different kinds based on when symptoms start:
- Acute Subdural Hematoma: This type comes on fast, usually within a day of a head injury. It’s very serious.
- Subacute Subdural Hematoma: Symptoms show up a few days to weeks after an injury. If not treated, it’s very dangerous.
- Chronic Subdural Hematoma: This type takes a long time to show symptoms, often months. It’s common in older people or those with blood clot issues.
Prevalence and Risk Factors
Older people, those on blood thinners, and heavy drinkers are more at risk. Head injuries, like from falls or car accidents, and blood clotting issues also increase the risk.
Knowing the risks and spotting the signs early can help a lot. This can make a big difference for those with this condition.
Causes of Closed Head Injury Subdural Hematoma
A closed head injury subdural hematoma often comes from a sudden, forceful head hit. This can cause the brain to shake inside the skull. This shaking might break a vein, leading to bleeding between the brain and its outer covering.
This bleeding forms a subdural hematoma. It happens when blood gathers in this space.
Many things can lead to these injuries:
- Falls: Older people often get hurt from falling and bumping their heads.
- Car Accidents: Being in a crash can cause a lot of damage to the head.
- Sports-Related Injuries: Playing sports like football or boxing can lead to head injuries.
- Violent Shaking: Shaking a baby too hard can hurt their brain and cause bleeding.
Age and health issues also play a big part. Older people are more likely to get hurt because their brains can move more in their skulls. Also, some medicines make bleeding more likely after a bump on the head.

Symptoms of a Closed Head Injury Subdural Hematoma
A closed head injury can cause a subdural hematoma. This can lead to many symptoms that may show up right away or later. It’s key to know these signs to get help fast.
Immediate Symptoms
Right after the injury, you might feel a bad headache, lose consciousness, and be very confused. These signs show you might have a subdural hematoma and you need to see a doctor quickly.
Delayed Symptoms
Sometimes, symptoms come later, like days or weeks after the injury. These can include memory problems, acting differently, trouble speaking, and feeling very tired. Keep an eye out for these signs to get medical help on time.

Diagnosis of Closed Head Injury Subdural Hematoma
Getting a closed head injury subdural hematoma diagnosed right is key. It helps in treating it well and prevents long-term problems. The first step is a detailed check-up to see how bad the brain injury is.
Initial Evaluation
The first check-up focuses on the brain and nervous system. Doctors use the Glasgow Coma Scale to see how awake the patient is. They check for any issues with eyes, speaking, and moving. This helps decide how quickly to act and what steps to take next.
Diagnostic Imaging Techniques
After checking the brain, doctors use scans to see the injury better. A CT scan is often used to spot blood in the brain and check for swelling. Sometimes, an MRI is needed for a closer look at soft tissues and other brain issues.
These scans and the first check-up give a full view of the patient’s condition. Using brain scans like CT and MRI helps spot any bleeding and brain damage. This lets doctors quickly start the right treatment.
Treatment Options for Closed Head Injury Subdural Hematoma
Treatment for a closed head injury subdural hematoma depends on the size, location, and severity of the bleed. Doctors will check and decide the best way to treat it. There are two main ways to treat it: surgery or not using surgery.
Surgical intervention might be needed to remove the blood clot and ease brain pressure. Doctors use craniotomy and burr holes for this. Craniotomy means taking a piece of the skull off to get to the clot. Burr holes are small holes made in the skull to drain the blood with less surgery.
For smaller cases, not using surgery might be enough. This means watching the patient closely and giving them medicine. Medication therapy helps with symptoms and keeps the brain pressure down. Doctors might give diuretics, corticosteroids, and anticonvulsants to reduce swelling, fight inflammation, and stop seizures.
Deciding between surgery or not depends on how the patient is doing and what the scans show. Sometimes, both methods are used together for the best results.
Here’s a quick look at the treatment options:
| Factor | Surgical Intervention | Conservative Management |
|---|---|---|
| Indications | Large hematomas, significant pressure on the brain, neurologic deterioration | Small hematomas, stable neurological status, mild symptoms |
| Common Procedures | Craniotomy, Burr holes | Close monitoring, Medication therapy |
| Recovery | Longer recovery period, potential ICU stay | Shorter recovery period, outpatient management |
| Risks | Infection, bleeding, brain swelling | Risk of hematoma expansion, monitoring challenges |
Recovery and Rehabilitation
Getting better from a closed head injury subdural hematoma takes time and effort. First, doctors focus on making sure you’re stable right after treatment. Then, they use different programs to help you get back to living well and doing things you can do.
Short-Term Recovery
Right after a closed head injury subdural hematoma, you need to focus on getting better quickly. Doctors keep a close watch and help you feel better. You might feel tired, dizzy, or have headaches at first.
How long it takes to get better depends on how bad the injury is and your health. The main goal is to get ready for more help later.
Long-Term Rehabilitation
Long-term rehab is key to fully recovering. It includes therapies like physical, cognitive, and neurorehabilitation. These help you do everyday things better.
Physical therapy helps with moving, balancing, and getting stronger. You might do exercises or stretches to help.
Cognitive rehab helps your brain work better. You’ll do special exercises to improve your memory, focus, and solving problems.
Neurorehabilitation is a mix of physical and brain therapies. It’s done by a team of experts who make a plan just for you.
| Type of Rehabilitation | Focus Area | Example Activities |
|---|---|---|
| Physical Therapy | Motor Skills, Strength, Balance | Exercises, Stretching, Endurance Training |
| Cognitive Rehabilitation | Memory, Attention, Problem-Solving | Memory Drills, Attention Exercises, Cognitive Tasks |
| Neurorehabilitation | Integrated Physical and Cognitive Functions | Multidisciplinary Therapy Programs |
How well you do in long-term rehab depends on the therapy quality and your effort. A good rehab plan can really help you recover from a closed head injury subdural hematoma.
Potential Complications
After a closed head injury, there are many possible problems. These can affect your health in many ways. They can cause issues with your brain and other health problems.
Neurological Complications
Seizures are a big worry after such an injury. They happen when the brain doesn’t work right. The injury can also cause permanent brain damage. This can change your life a lot.
It’s also possible for the hematoma to come back. So, you need to keep seeing your doctor. Closed Head Injury Subdural Hematoma
Other Health Risks
There are other health risks too. One is hydrocephalus, which means too much fluid in the brain. This can make brain health worse.
Cognitive deficits are also a concern. They can affect your memory and focus. Getting help from rehab and doctors is key to getting better.
Prognosis and Outcome
The outcome after a closed head injury with a subdural hematoma varies a lot. It depends on several key factors. These include the patient’s age, health, how severe the injury is, and how quickly they get treatment. Knowing these things helps plan for recovery and care.
Many people die from this injury, especially if it’s very severe or if they don’t get help fast. But, if they do get quick and good medical care, many can recover well. The size of the bleed and the first Glasgow Coma Scale score are very important. They help predict how well someone will do and if they’ll get better.
Long-term, how well someone does depends on the brain damage and how well they can get better through rehab. Some people get back to doing everything they could before the injury. Others may have ongoing problems. Doctors say it’s key to have a rehab plan that fits the patient to help them get better and live a good life after the injury.
